Habitrail Ovo Window

Habitrail OVO Windows allow you to block off pathways, while maintaining maximum air circulation, thanks to air vents located all along the perimeter of each window. This replacement pack includes 3 colourful (red, blue and lime) OVO Windows.
The complete line of Habitrail OVO housing and accessories is based on extensive behavioral studies of pet hamsters and is designed to help enhance their quality of life. Completely redesigned, re-tooled and reinvigorated, OVO brings even more interesting and entertaining venues in which hamsters can explore, burrow, snooze, exercise or simply chill out.
